CAUTION: Before executing any recovery or update procedure with the RM tool, it is recommended to back
up the current configuration. You can use the backup option in the Cluster Services tab on the CSN console to
backup the current configuration.
a) Enter the access code and follow the on-screen instructions.
A screen is displayed which shows the versions of the RM and the DX system.
b) Click Next.
RM determines if data recovery is possible.
c) Do one of the following:
*
If data recovery is possible, click Reboot to restart the system. The RM completes installing the DX
system software, drivers, and firmware. After the installation is complete, a message is displayed
prompting you to restart the system. After restarting, the DX system is installed and ready for initial
configuration.
*
If data recovery is not possible, an error message is displayed. Re-run the RM in Factory mode and
follow the instructions in step 4.
The RM saves all the user settings at: /u01/system_recovery_data/
NOTE: The Backup Manifest UUID is saved in the /u01/system_recovery_data/bootstrap file. This information is
required to reconfigure the CSN. The other UUID is contained within (the saved) cluster.cfg file which contains the
cluster settings.
NOTE: Manual steps must be followed to reconfigure the CSN with the saved settings. For more information on
completing the recovery process, see
